* Some things are currently ifndef'd out completely for x86_64 because
they aren't implemented, there's a few other ifdef's to handle x86_64
differences but most of the code works unchanged.
* Renamed some i386_* functions to x86_*.
* Added a temporary method for setting the current thread on x86_64
(a global variable, not SMP safe). This will be changed to be done
via the GS segment but I've not implemented that yet.
For now I've just put all the stub functions that are needed to link the
kernel into a file called stubs.cpp. I've not yet moved across the interrupt
handling code or the ELF64 relocation code to the x86 directory. Once those
have been moved I can get rid of the x86_64 headers/source directories.
Not many changes seeing as there's not much x86_64 stuff done yet. Small
differences are handled with ifdefs, large differences (descriptors.h,
struct iframe) have separate headers under arch/x86/32 and arch/x86/64.
The setup procedure is fairly simple: create a 64-bit GDT and 64-bit page
tables that include all kernel mappings from the 32-bit address space, but at
the correct 64-bit address, then go through kernel_args and changes all virtual
addresses to 64-bit addresses, and finally switch to long mode and jump to the
kernel.
Introduce a function to generate the string representation of a bitrate
(kbps, mbps, gbps, etc..)
* Factor out the code from MediaPlayer InfoWindow
* Allow different bases (/1000 or /1024)
* platform_allocate_elf_region() is removed, it is implemented in platform-
independent code now (ELF*Class::AllocateRegion). For ELF64 it is now
assumed that 64-bit addresses are mapped in the loader's 32-bit address space
as (address - KERNEL_BASE_64BIT + KERNEL_BASE).
* mapped_delta field from preloaded_*_image removed, now handled compile-time
using the ELF*Class::Map method.
* Also link the kernel with -z max-page-size=0x1000, removes the need for
2MB alignment on the data segment (not going to map the kernel with large
pages for the time being).
The ELF loader now uses a new platform function, platform_allocate_elf_region,
which returns 2 addresses: the real load address and an address where the
region is mapped in the loader's address space. All of the ELF loading code
has been changed to access the load region through the mapped address rather
than the addresses contained in the ELF image. The ELF64 version of
platform_allocate_elf_region on x86 uses the existing MMU code, which maps
everything at 0x80000000, but returns the correct 64-bit address. The long
mode switch code will just set up the 64-bit address space with everything
remapped at the correct address.
* FixedWidthPointer:
- operators ==/!=: Change second operand type from void* to const
Type*. Also add non-const version to resolve ambiguity warning when
comparing with non-const pointer.
- Add Pointer() getter.
- Remove templatized cast operators. They are nice for casting the
pointer directly to another pointer type, but result in ambiguity.
* Make preloaded_image::debug_string_table non-const. Avoids clashes of
the const and non-coast FixedWidthPointer comparison operators. A
cleaner (but more verbose) solution would be to spezialize
FixedWidthPointer for const types.
The actual implementation of the ELF loading methods have been put into
an ELFLoader template class that takes a single template parameter, which
is a structure containing all the necessary ELF typedefs. It's a bit
verbose, but I thought it was a neater solution than using a bunch of
standalone functions with a huge number of template parameters. There is
no change to code outside of elf.cpp, the ELF32/ELF64 differences are
handled internally.
* There is now 2 structures, preloaded_elf32_image and preloaded_elf64_image,
which both inherit from preloaded_image.
* For now I've just hardcoded in use of preloaded_elf32_image, but the
bootloader ELF code will shortly be converted to use templates which use
the appropriate structure. The kernel will be changed later when I add
ELF64 support to it.
* All kernel_args data is now compatible between 32-bit and 64-bit kernels.
* Added a FixedWidthPointer template class which uses 64-bit storage to hold
a pointer. This is used in place of raw pointers in kernel_args.
* Added __attribute__((packed)) to kernel_args and all structures contained
within it. This is necessary due to different alignment behaviour for
32-bit and 64-bit compilation with GCC.
* With these changes, kernel_args will now come out the same size for both
the x86_64 kernel and the loader, excluding the preloaded_image structure
which has not yet been changed.
* Tested both an x86 GCC2 and GCC4 build, no problems caused by these changes.
I've tested this change on x86, causing no issues. I've checked over the code
for all other platforms and made the necessary changes and to the best of my
knowledge they should also still work, but I haven't actually built and
tested them. Once I've completed the kernel_args changes the other platforms
will need testing.
Pointers in kernel_args are going to be changed to unconditionally use 64-bit
storage (to make kernel_args compatible with both the x86 and x86_64 kernels).
KMessage stores a pointer to its buffer, however since KMessage is used
outside of the boot code it is undesirable to change it to use 64-bit storage
for the pointer as it may add additional overhead on 32-bit builds. Therefore,
only store the buffer address and size and then construct a KMessage from
those in the kernel.
The whole kernel now builds and there are no undefined references when
linking, I just need to fix some strange relocation errors I'm getting
(probably a problem with the linker script) and then I'll have a kernel
image.
Since ICI arguments are used to send addresses in some places, uint32 is
not sufficient on x86_64. addr_t still refers to the same type as uint32
(unsigned long) on other platforms, so this change only really affects
x86_64.
* x86_64 is using the existing *_ia32 boot platforms.
* Special flags are required when compiling the loader to get GCC to compile
32-bit code. This adds a new set of rules for compiling boot code rather
than using the kernel rules, which compile using the necessary flags.
* Some x86_64 private headers have been stubbed by #include'ing the x86
versions. These will be replaced later.
* gPeripheralBase keeps track of the device
peripherals before and after mmu_init
* Add ability to disable mmu for troubleshooting
* Remove static FB_BASE, we actually don't know
where the FB is yet. (depends on firmware used)
* BCM2708 defines no longer assume 0x20 address
We will be throwing away the blob memory mapping
and using our own.
* Use existing blob mapping to turn GPIO led on pre mmu_init
* Remap MMU hardware addresses from 0x7E. We could map each device,
however the kernel will throw away the mappings again anyway. For
now we just map the whole range and use offsets.
* Serial uart no longer works, however at least
we know why now :). Serial driver now needs to
use mapped address.
* Use U-Boot mmu code as base
* This will be factored out someday into common arch mmu
code when we can read Flattened Device Trees
* Move mmu_init after serial_init.
Temporary change as we will want serial_init to use
memory mapped addresses... for debugging.
* introduce a DebugUART baseclass,
* rework 8250 and PL011 implementations from kallisti5 to inherit DebutUART,
* each arch should override the IO methods to access registers.
* on ARM registers are 32bit-aligned.
* U-Boot still works for the verdex target.
* rPi still compiles, needs testing.
* Still some more consolidation needed to allow runtime choice of the UART type (as read from FDT blobs for ex.).
* serial.cpp should probably mostly be made generic as well.
* didn't touch x86 or ppc yet.
* Enable/Disable makes more sense and matches
platform loader serial functions.
* Rework PL011 code after finding a PDF covering
the details of it.
* Rename UART global defines in loader to be more
exact about location
* This makes things a little more flexible and
the interface to use the uarts cleaner.
* May want to make a generic Uart wrapper
class in uart.h / uart.cpp and call drivers
as needed from there.
* Avoid name collisions
* This uart stuff may work better as a class at
some point, however I didn't want to rock the
u-boot boat *too* much as I don't have the
hardware to test.
* Add nested function wrappers to allow usage of other
uart drivers depending on board. We may want to use this
on other platforms at some point (haha, maybe)
* Make Kernel ARM UART slightly more generic
through (BOARD_UART_CLOCK) configured per board
* Add initial Raspberry Pi serial code
* Still rough and non-working
* Change ShowTip() point parameter name to where.
* Add a parameterless ResetWindowFrame() overload that get's the current
where and calls ResetWindowFrame(BPoint where) which does the actual
work. FrameResized() calls this parameterless ResetWindowFrame()
method instead of doing the work in that method. This is functionaly
the same but allows me to call the parameterless ResetWindowFrame()
elsewhere.
* The areas allocated for BBitmaps were never deleted, even though the
app_server deleted its part when the memory got freed.
* This resulted in a constant memory increase if the application in question
would operate on many changing large bitmaps, like photos.
* Since the bitmaps are reference counted, we don't actually know when to delete
the areas, so that the app_server now notifies the client whenever that is
possible.
* This might fix#6824.
* This removes the fVisibleToolTip member from BView, and fixes bug #5669;
BToolTipManager::ShowTip() now gets the owner of the tool tip as an extra
parameter.
* Removed the work-around to hide that bug.
* Improved ToolTipTest application to include more test cases like a view that
periodically update its tool tip via SetToolTip(const char*), and one that
sets a new tool tip every second.
* Furthermore, added a test that shows that inner views inherit the tool tip
of their parents.
* Fixed another bug in BToolTipManager::ShowTip() that would release an
extra reference to the tool tip currently shown.
* First steps at getting card command processor wired
up to the ring buffers.
* Code doesn't run yet as I have *no* idea what happens
when these rings are in an invalid state.
* rename B_TRANSLATE_CONTEXT to B_TRANSLATION_CONTEXT and
B_TRANSLATE_WITH_CONTEXT to B_TRANSLATE_CONTEXT, squashing a TODO
* adjust all uses of both macros in Haiku's source tree
* use correct header guard for collecting/Catalog.h
The renamed macros require adjustments to all external applications
using catalogs.
* move versions of the B_TRANSLATE_...-macros used during collecting
of catalog keys to a specific header file, which will only be picked
up when running collectcatkeys
* fix a couple of build problems during the preprocessing of the libbe-
sources when extracting catalog keys, all due to private headers not
being found
* move ZombieReplicantView.h from kits/interface to
headers/private/interface, as this way it can be picked up when
building the libbe catalog
* rename BCatalogAddOn to BCatalogData, since it doesn't represent an
add-on, but rather the catalog data provided by an add-on
* move BCatalogData out of Catalog.{h,cpp} into its own header and
implementation file
* drop BCatalogData::MarkForTranslation() methods, they're not needed
* drop BCatalog::GetNoAutoCollectString() methods, they're not being
used anywhere
* cleanup the B_TRANSLATE_... macros somewhat
* add versions of the B_TRANSLATE_MARK_... macros that are meant to be
used in void context (when the string isn't being used by the program,
just meant to be picked up by collectcatkeys).
* adjust several apps to use B_TRANSLATE_MARK_..._VOID where needed
* adjust users of BCatalogAddOn accordingly
* it's bad practice to do a 'using <namespace>' in a header, as that
is very likely to have unintended effects, so drop those from a couple
of private Locale headers
* adjust files all over the locale kit in order to fix the problems
(by explicitly importing the required classes in the implementation
files)
* move EditableCatalog to its own header and implementation file
* move problematic BCatalog::CatalogAddOn() to EditableCatalog
* adjust Locale tools accordingly
AMD C1E is a BIOS controlled C3 state. Certain processors families
may cut off TSC and the lapic timer when it is in a deep C state,
including C1E state, thus the cpu can't be waken up and system will hang.
This patch firstly adds the support of idle selection during boot. Then
it implements amdc1e_noarat_idle() routine which checks the MSR which
contains the C1eOnCmpHalt (bit 28) and SmiOnCmpHalt (bit 27) before
executing the halt instruction, then clear them once set.
However intel C1E doesn't has such problem. AMD C1E is a BIOS controlled
C3 state. The difference between C1E and C3 is that transition into C1E
is not initiated by the operating system. System will enter C1E state
automatically when both cores enters C1 state. As for intel C1E, it
means "reduce CPU voltage before entering corresponding Cx-state".
This patch may fix#8111, #3999, #7562, #7940 and #8060
Copied from the description of #3999:
>but for some reason I hit the power button instead of the reset one. And
>the boot continued!!
The reason is CPUs are waken up once power button is hit.

* Make the locale kit a part of libbe.
* Drop the LocaleBackend kludge used from within libbe (and from
other places, too) in order to access system catalog strings.
This is now done via gSystemCatalog, which is provided and initialized
by libbe.
* Drop all references to liblocale.so from all Jamfiles.
* Add legacy symlink liblocale.so in order to keep optional packages
that rely on it in a working state.
TODO: the documentation hasn't been updated.
* The AtomBIOS timeout fix has made my DP bridge
stop working
* The current DisplayPort code is a little lacking
on DP link training... I think thats the cause.
* This puts the first steps towards DP training
in place.
* I plan on trying to make some of this DP stuff
common accelerant stuff after it works.
